Intended Use
The SIGNA PET/MR system combines magnetic resonance diagnostic devices (MRDD) and Positron Emission Tomography (PET) scanners that provide registration and fusion of high resolution physiologic and anatomic information, acquired simultaneously and isocentrically. The combined system maintains independent functionality of the MR and PET devices, allowing for single modality MR and / or PET imaging. These systems are intended to be utilized by appropriately trained health care professionals to aid in the detection, localization, and diagnosis of diseases and disorders. MR is intended to produce transverse, sagittal, coronal and oblique cross-sectional MR images, spectroscopic images and/or spectra, and displays the internal structure and/or function of the human body. Other physical parameters derived from the images and/or spectra may also be produced. Depending on the region of interest, approved contrast agents may be used, as described in their labeling. This system may also be used for imaging during interventional procedures when performed with MR compatible devices, such as MR safe biopsy needles. PET images and measures the distribution of PET radiopharmaceuticals in humans to aid the physician in determining various metabolic (molecular) and physiologic functions within the human body for evaluation of diseases and disorders such as, but not limited to, cardiovascular disease, neurological disorders and cancer. The combined system utilizes the MR for radiation correction maps for PET studies. The system provides inherent anatomical reference for the fused PET and MR images due to precisely aligned MR and PET image coordinate systems.
Device Description
The GE SIGNA PET/MR system is a combined Magnetic Resonance Diagnostic Device (MRDD) and Positron Emission Tomography (PET) scanner. The system is designed for whole body oncology, neurology and cardiology examinations. The SIGNA PET/MR system provides simultaneous acquisition of high resolution metabolic and anatomic information from the two major components of each system (MR and PET). Additional components of the system include: a detachable patient table and both the acquisition and processing workstations with associated software. The SIGNA PET/MR includes a 3.0T superconducting magnet, gradient coil and a transmit/receive whole body radiofrequency coil. The system includes patient adaptable RF shimming capabilities. The SIGNA PET detectors are integrated into the MR bore. This allows for simultaneous, precisely aligned whole body MR and PET acquisitions. The PET subsystem supports Time of Flight (ToF) coincidence detection. The SIGNA PET/MR software is used for patient management, data management, scan control, image reconstruction and image archival and evaluation. All images conform to DICOM imaging format requirements. The modifications to this system include the MotionFree Brain software feature, which allows users the flexibility to correct patient head motion using the acquired PET data from the exam, without the need of external tracking devices, additional MR data, or other motion tracking data schemes.
More Information

Not Found

No
The summary describes image processing techniques for motion correction but does not explicitly mention or describe the use of AI or ML algorithms. The "Mentions AI, DNN, or ML" field is "Not Found".

No
The device is described as aiding in the detection, localization, and diagnosis of diseases and disorders, which is a diagnostic function, not a therapeutic one.

Yes

The "Intended Use / Indications for Use" section explicitly states that the system is "intended to be utilized by appropriately trained health care professionals to aid in the detection, localization, and diagnosis of diseases and disorders." It also describes how both the MR and PET components provide information for diagnostic purposes. Additionally, the "Device Description" calls it a "combined Magnetic Resonance Diagnostic Device (MRDD) and Positron Emission Tomography (PET) scanner."

No

The device is described as a combined Magnetic Resonance Diagnostic Device (MRDD) and Positron Emission Tomography (PET) scanner, which are hardware components. While it includes software, it is an integral part of a larger hardware system.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • IVDs analyze biological samples: In Vitro Diagnostics are designed to examine specimens taken from the human body, such as blood, urine, or tissue, outside of the body (in vitro).
  • This device performs imaging: The SIGNA PET/MR system is an imaging device that uses Magnetic Resonance and Positron Emission Tomography to visualize the internal structure and function of the human body in vivo (within the living body).
  • The intended use describes imaging and diagnosis based on imaging: The intended use clearly states the system is used to produce images and measure the distribution of radiopharmaceuticals to aid in the detection, localization, and diagnosis of diseases and disorders. This is achieved through imaging, not through the analysis of biological samples.

Therefore, the SIGNA PET/MR system falls under the category of medical imaging devices, not In Vitro Diagnostics.

| | provides inherent anatomical reference for the fused PET
and MR images due to precisely aligned MR and PET
image coordinate systems. |
| Comparison of
Technological
Characteristics: | The SIGNA PET/MR with the proposed software feature
employs the same fundamental technology as the
predicate device. |
| | The SIGNA PET/MR has been modified to include the
MotionFree Brain feature. The user interface provides
operators of the system with an option for enabling this
feature. MotionFree Brain derives head motion
information from the PET data; there is no need for
external tracking devices, additional MR data, or
additional PET data collection. The feature measures
and incorporates the rigid-body motion information into
the PET reconstruction, correcting the position of each
coincidence event to account for patient head motion. |
| | These technological differences do not raise any different
questions regarding safety and effectiveness. Both
devices must allow for an effective method to setup an
appropriate scan prescription. The performance data
described in this submission include results of both bench
testing and clinical testing that show the performance of
the SIGNA PET/MR compared to the predicate device. |
| Summary of Nonclinical
Testing: | The following quality assurance measures were applied
to the development of the device:
• Risk Analysis
• Requirements Reviews
• Design Reviews
• Verification (functional testing for subsystem and
system integration)
• Validation (simulated use testing) |
| | Non-clinical tests have been summarized in the
verification and validation testing. The testing was
completed with passing results per the pass/fail criteria
defined in the test cases. This supports
substantial equivalence to its predicate because the
software feature was developed under quality assurance
Design Controls. Performance testing on phantoms as
part of non-clinical testing demonstrated MotionFree
Brain achieved performance claims for Quantitation,
Temporal Resolution, and Spatial Accuracy. |
| | |
| Summary of Clinical
Testing: | An external reader evaluation study was performed for
MotionFree Brain. The retrospective blind study involved
board-certified readers who were asked to evaluate
randomly labeled cases that were reconstructed with and
without MotionFree Brain. Verification documents, validation documents, and test
reports have been provided for more details. Testing
demonstrated that the device is as safe, as effective, and
performs as well as or better than the predicate device.
No new questions of safety and effectiveness were raised
during nonclinical testing. |
| | The readers were blinded to feature use (e.g. whether
feature was enabled or disabled), report case history, as
well as to the assessments made by the other readers.
The readers were asked to complete an assessment,
including additional commentary, and report their
preference on the pair of image series presented. |
| | Clinical testing confirms that MotionFree Brain can be
used safely and effectively in a clinical setting. |
| Conclusion Drawn from
Performance Testing: | The SIGNA PET/MR with the modified software feature
has the same intended use as the predicate. This 510(k)
submission includes information on the technological
characteristics of the proposed software feature, as well
as performance data demonstrating that the feature is as
safe and effective as the predicate, and does not raise
different questions of safety and effectiveness. |
| | In conclusion, GE Healthcare considers the SIGNA
PET/MR to be at least as safe and effective, and its
performance is substantially equivalent to the predicate
device. |
